CHURN.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed. June 15, 1909. Serial No. 502,312.

To all whom it may concern:

Be it known that we, FRANK O. HOMME, JOSEPH T. VoLLnN, and ISAAC L. IsAAcsoN, citizens of the United States, residing at Kloten, in the county of Nelson and State of North Dakota, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in churns of the revolving barrel and angular box type.

One object of the invention is to provide a churn of this character having a stationary dasher and improved means for mounting and adjusting it.

Another object of the invention is to provide improved means adapted to be readily applied to ordinary revolving barrel and angular box churns for providing them with stationary dashers.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a plan view of the improved churn; Fig. 2 is an end view; Fig. 3 is a vertical longitudinal section; Fig. 4 is a perspective View of one of the bearings for the rotary body and showing the anchoring member for the stationary dasher; Fig. 5 is an end view of the stationary dasher; Fig. 6 is a detail section taken on the plane indicated by the line 66 in Fig. 5; Fig. 7 is a perspective view of the spring shown in Fig. 5; Fig. 8 is a perspective view of the anchoring plate shown in Fig. 5; Fig. 9 is a perspective view of the pivot plate which is secured in the body to support one end of the dasher; and Fig. 10 is a detail perspective of the socket and plate on the inner end of the anchoring shaft.

In the drawings 1 and 2 denote two up rights or standards which may rise from a suitable base and which have rotatably mounted in their upper ends a churn body 3. The latter may be in the form of a barrel, an angular box or of any other form and construction. Secured to one end of the body by means of an attaching flange 4 and screws passed therethrough, is a journal 5 which is removably arranged in a bearing notch or recess at the upper end of the standard 2 and which has on its outer end a crank handle 6 or other means by which the body of the churn may be rotated. 7 denotes the journal for the other end of the body 3, said journal being tubular and having intermediate its ends an attaching flange 8 which is secured by screws or other fastenings to the end of the body. The outer end of the journal 7 is removably arranged in a bearing notch or recess in the top of the standard 1 and the inner end of said journal projects through a centrally arranged opening 9 in the end or head of the body 3.

The journal 7 is made tubular to receive an anchoring rod or shaft 10 for a stationary dasher 11. The portion of the shaft 10 within the journal 7 is cylindrical so that said journal may rotate upon it and its projecting outer end is provided at opposite points with fiat faces 12 to enter the re- .cessed or notched upper end of an anchoring bracket 13 which is secured to the standard 1. Said shaft 10 is retained in the journal 7 by providing on the outer portion of said shaft a stop collar 14 which may be in the form of a washer held in place by a cross pin 15, and having a spring washer 16 interposed between said washer and pin.

Formed on the inner end of the shaft 10 is an enlargement or circular plate 17 having a socket in which is supported one end of the dasher 11. The latter, it will be understood, may be of any form and construction but as illustrated consists of two X- shaped heads 18, the arms and intermediate portions of which are united by longitudinal bars 19. To adjustably and removably mount the dasher within the body 3 of the churn, a pivot screw 20 is arranged in the center of one of the heads 18 and has at its end a bearing recess for a pivot stud 21 arranged on a plate 22 which is secured to the inner face of the adjacent end or head of the body by screws 23 passed through said plate and by spurs 24 formed integral with the latter. The screw 20 is arranged in a nut 25 set in said head 18 and on its inner end is a notched head by means of which it may be turned. A look nut 26 is also provided on said screw to retain it in adjusted position. The other end of the dasher 11 is detachably mounted by providing in the center of its head 18 a screw 27 with a squared or flat faced head 28 at its outer end to enter a similar-shaped socket 29 formed in an enlargement 30 011 the head or plate 17. Said screw 27 is prevented from rotating by providing upon its outer portion an apertured attaching plate 31 which bears against one of the arms of the head 18 and is secured against movement by a screw or similar fastening 32. The socket 29 is open on one side to permit of the ready insertion and removal of the head 28 and, in order to retain said head in the socket, recesses or seats 33 are provided in the outer edges of the opposing walls of the sockets 29 to receive a semi-cylindrical lug 34; formed on the center of a leaf spring 35, which latter is set in a recess in the head 18 and has its ends secured, as at 36. T he ends of the walls of the socket 29 which contain the recesses or seats 33 are rounded, as shown at 37, so that the lug 3% may be easily sprung into one of said seats. By mounting the dasher in this manner, it will be seen that it may be readily applied by placing the screw 20 over the pivot 21 and then pushing the head 28 down into the socket 29 so that the lug 3l on the spring 35 will spring into one of the seats 33 and thereby retain the head 28 in the socket 29. By reversin this operation, the dasher may be readily removed from the churn body for cleaning purposes. By adjusting the screw 20 wear may be taken up, the tension of the spring 35 may be varied so that the dasher will be effectively retained in proper position and the plate or nut 17 will be pressed against the journal 7 to provide a liquid tight oint at this point. From the foregoing it will be seen that the invention provides an exceedingly simple and practical revolving barrel or angular box churn, the parts of which may be produced at a small cost and will be strong and durable. Wear upon the parts may be readily taken up by the screw 20 and by mounting the dasher as set forth it may be readily removed for cleaning purposes and the body of the churn may be also readily removed from its supporting standards.

The several attachments may be applied to new churns in their course of manufacture or they may be readily applied to old revolving barrel and angular box churns so as to equip the latter with the stationary dasher, it being understood, of course, that the shape of the attaching flanges for the journals will vary according to the shape of the barrel or box to which such journals may be fastened.

The head 28 is formed with a transverse opening which is adapted to receive a pin which may serve the purpose of the spring 3-l should the latter break.

\Vhile the preferred embodiment of the invention has been shown and described in detail, it will be understood that we do not wish to be limited to the precise construction set forth since various changes in the form, proportion and arrangement of parts and in the details of construction may be resorted to within the spirit and scope of the invention.

Having thus described the invention what is claimed is:

A churn con'rprising a support, a revolving body j ournaled thereon and having a tubular journal, means for revolving said body, a stationary shaft extending through the tubular journal and into one end of the body, means for anchoring the outer end of said shaft, a socket upon the inner end of said shaft, a stationary dasher having at one end a head to enter said socket, a spring device for retaining said head in said socket, and means for supporting the other end of the dasher from the opposite end of the body.

2.
